The image above shows a 'suspended-load backpack' which was recently developed by Lawrence Rome, a biologist at the University of Pennsylvania. The luggage compartment travels up and down on the frame as the user walks, turning a gear which drives a small generator. The amount of power generated depends on how much weight is in the pack and how fast the user walks. Researchers measured a maximum output of 7.4 watts. Seven watts is sufficient to power a handful of electronic gadgets at the same time, including a cell phone, an MP3 player, a handheld computer, night-vision goggles, and a water purifier. Wow, shout out to all you UPENNer's. We need more ideas like this so we don't use up all the fossil fuels and completely melt the earth. Just think i could walk around the city all day, and power all my tech toys. Sweeeeeet. Where can i get one?
